A selfconsistent unstructured solver for weakly ionized gases modeling inviscid multi-species conservation equations coupled with a reduced state-to-state kinetics model is presented. Mathematical model have been implemented in EulFS, a CFD unstructured solver using Residual Distribution Schemes, to discretize convective fluxes and chemical source terms. A simple model which couples the weakly ionized gas with an electric field controlled by considering a power supply and an external circuit resistence Rc is considered. Preliminary results will be shown for an argon plasma considering different 2D and 3D geometrical configurations.

Abstract
A selfconsistent unstructured solver for weakly ionized gases modeling inviscid multi-species conservation equations coupled with a reduced state-to-state kinetics model is presented. Mathematical model have been implemented in EulFS, a CFD unstructured solver using Residual Distribution Schemes, to discretize convective fluxes and chemical source terms. A simple model which couples the weakly ionized gas with an electric field controlled by considering a power supply and an external circuit resistence Rc is considered. Preliminary results will be shown for an argon plasma considering different 2D and 3D geometrical configurations.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
